smallValuesGrouping

If you need to group specific chart segments into one, use the options of the smallValuesGrouping configuration object.

You can group segments in two different modes. Use a 'topN' mode to group all segments that have an index that is equal to or greater than the value of the topCount option. To group all segments with the value less than the value of the threshold option, use a 'smallValueThreshold' mode.

By default, the resulting segment is called "others". To change this name, specify the groupName option.

threshold

When you use the 'smallValueThreshold' grouping mode, specify a value that will serve as a threshold for chart segments. All segments with a value less than the threshold will be grouped into the "others" segment.
